Customer Questions & Answers

  1. Q Will this adhere to aluminum frames?
    Answered by the admin


  2. Q Can I prime all window sash parts - stiles, rails, and muntins before the application of the glazing? Or do you get better bond strength glazing directly to raw wood and then prime?
    Answered by the admin

    You should always prime the bare wood before using the glazing compound.

  3. Q Can't calcium carbonate or pumice be brushed over the glazing to achieve a fast skin over (in under 24 hours) ?
    Answered by the admin

    No. The Glazing Compound takes 2-3 weeks to skin over.

  4. Q Question/clarification on inside/shop application ONLY of Type M. If the TypeM is applied to a wooden sash that is protected by a good quality storm window, can the sash be reinstalled during the curing period? The TypeM will be exposed to direct sunlight, (albeit post fall equinox angles) and temperature swings between 45&75 (Sept/Oct in Ohio). But the storms will protect the TypeM from rain
    Answered by the admin

    The window should not be put outside after application of the Type M until it has skinned over.

  5. Q I’m reglazing wood windows in 1925 house. Read on many websites “Type M” is best. Here it says only for inside shop use? Is this not suitable for general window glazing (glazing is on outside of window)? Also having a hard time finding a supplier near me. Ones listed don’t sell product I need. Can I buy a quart off your website?
    Answered by the admin The Sarco Type M is for indoor use only. It must be applied indoors, allowed to skin over (usually within 14 days) and then you can take the window outside. We only sell the product in a one gallon size.
